摘要
为了提高图像信息处理速度,利用光电混合实现的方法,将光学小波变换应用于视觉系统设计.依据4f相关器光学信息处理的原理,在频域内通过计算机编码,在电寻址空间光调制器上,构建不同类型的小波函数滤波器库,对目标的图像特征进行提取与辨识.研究结果表明,基于光学小波变换视觉系统正确可行.在图像特征提取中,以光波传递信息可以提高视觉信息处理的速度.
Abstract
In order to enhance the speed of image processing , the optic wavelet transform is applied to design of vision system based on the method of photoelectric hybrid implementation. Using the theory of optical information processing of 4f correlator, a library of wavelet function filters on the spatial light modulator with electro-address is constructed. It is achieved by computer programming in the spatial frequency domain, so the features of object can be extracted and recognized. The research results show the optic wavelet transform based vision system is reasonable and feasible. Optical information based image feature extraction will enhance the speed of vision information processing.
